The cast of Celeste and Jesse Forever hit the Sundance Film Festival to show off their sweet movie on Friday. It's Rashida Jones's first screenplay, and she also stars alongside Andy Samberg in the project. On the red carpet at their premiere, the two gushed about working together, and Andy joked that if he was tasked with winning back an old love in real life, he'd probably revert to "d*ck in a box" tactics. Emma Roberts plays a pop star in Celeste and Jesse Forever and to get ready for the part she revealed that she channeled a little bit of Christina Aguilera in the "Dirrty" days, Britney Spears, and Ke$ha. We also chatted with Elijah Wood about his part in Celeste and Jesse and what it was like to see the The Hobbit trailer for the first time, which he said was "electrifying." Award season darling and The Descendants star Shaliene Woodley slipped in to see the movie, and later in the evening checked out Wiz Khalifa at the Bing Bar.
